What It Is

This is a 40V 6000mAh aftermarket lithium-ion battery replacement designed for Ryobi 40V cordless lawn mowers, trimmers, blowers, and other OPE tools. It comes as a 2-pack and is meant to replace OEM models OP4050A, OP4015, OP4026, OP40201, OP40261, OP4030, OP40301, OP4040, OP40401, OP4050, OP40501, and OP40601.

Fitment & Compatibility

• Brand & Model: Works with any Ryobi 40V tool that accepts the standard “slide-in” battery interface (common on Ryobi 40V mowers, string trimmers, blowers, chainsaws, etc.). Does not fit Ryobi 18V or 36V systems.
• Physical Check: Measure your existing battery’s length, width, and thickness—this pack is roughly 6.5 x 3.5 x 4 inches. Ensure your tool’s battery compartment has enough clearance (some older mower decks may be tight).
• OEM vs Aftermarket: This is a third-party replacement, not Ryobi-branded. It may have slight dimensional differences that affect fit on some mowers with narrow battery bays.
• Voltage & Capacity: 40V nominal, 6000mAh (216Wh). Confirm your tool supports this capacity—most Ryobi 40V tools do, but very old models may have lower max capacity limits.

Key Things to Know

• Quality & Safety: Aftermarket batteries often use lower-grade cells. Check for UL or CE certification marks on the battery label to reduce fire risk.
• Installation: No tools required—slides directly into the battery port. Ensure the locking tabs click fully into place.
• Run Time vs OEM: 6000mAh is higher than most Ryobi OEM batteries (e.g., OP4050A is 4000mAh). You’ll get longer runtime, but charging time may be longer if using a standard Ryobi charger.
• Common Gotcha: Some users report the battery fits loosely or requires slight pressure to seat. If your tool vibrates heavily (e.g., a mower), a loose connection can cause intermittent power loss.

Should You Buy It

Buy this if you need a budget-friendly 2-pack for light to medium use on multiple Ryobi 40V tools and don’t mind slightly looser fitment. Avoid if you rely on a single mower for heavy-duty cutting—invest in OEM for better reliability and warranty support.
